• SF6 Gas Density Meter For Gas Insulated Switchgear

  This type SF6 gas density meter is used to display the density of SF6 gas in closed containers on site. It is used in electrical equipment such as SF6 circuit breakers, pole-mounted switches, inflatable cabinets, transformers and mutual inductors. Provide solutions for new substations and intelligent transformation of existing substations.

  Installation Precautions
  1. The instrument must be installed vertically on the interface of the device.
  2. During installation, a wrench must be used to tighten the joint nut. It is strictly prohibited to rotate the meter head to fix it.
  3. The instrument should slowly raise and lower the pressure to prevent product damage.
  4. When the density meter is in normal use, loosen the explosion-proof cap on the housing 1-2 turns to make the inner cavity
  The air is connected, and then tighten it.
  Note: When the density meter is not in use, the temperature compensation is in a non-temperature compensation equilibrium state, and the pointer changes with the ambient temperature.
  changes with degree.
  When the temperature is higher than 20°C, the pointer is below the 0-bit line.
  When the temperature is below 20°C, the pointer is above the 0 bit line.
